My ex wants to come over?

We broke up a couple weeks ago, we've been texting everyday and he says he misses me and wants to work things out but we have to hangout and talk first. So tonight he is coming over.. Not sure if he's gonna stay but he said if he does he's skeeping on the couch. He also said "but I want to have sex... I miss yours" why would he want to sleep on the couch then? (I'm not having sex with him.. I know he's probably just going to use me if I do have sex) he isn't going to fool me this time.. I'm not letting him hurt me again.. So what do you guys think his deal is?
